@camscott Fitbit recently added Outdoor Workout as an exercise shortcut on the Sense and Versa 3. It has GPS and is designed for activities like kayaking and SUP. This is the correct shortcut. Please disregard the fact that the icon is the same one as the Interval Workout icon. Fitbit is aware of this. I hope this helps.
